To users of the EOS 7D, EOS 40D, EOS 50D, and EOS 60D Digital SLR

When using certain zoom lenses released between 1990 and 1995 with any of these cameras, the peripheral AF points do not function as cross-type AF points.

Thank you for using Canon products.

When using any of eight zoom lenses listed below released between 1990 and 1995 with any of the below cameras, the peripheral AF points do not function as cross-type AF points, resulting in vertical and horizontal lines not being simultaneously detected. Vertical or horizontal lines can only be detected separately.

We would like to apologize for not including this information in the user’s manuals of the affected cameras, and the details of this matter are as described below.

Affected cameras:

EOS 7D
EOS 40D
EOS 50D
EOS 60D
Affected lenses:

EF35-80mm F4-5.6
EF35-80mm F4-5.6 II
EF35-80mm F4-5.6 III
EF35-80mm F4-5.6 USM
EF35-105mm F4-5.6
EF35-105mm F4-5.6 USM
EF80-200mm F4.5-5.6 II
EF80-200mm F4.5-5.6 USM

Phenomenon: 
When using any of the affected cameras in combination with any of the affected zoom lenses, the peripheral AF points do not function as cross-type AF points resulting in vertical and horizontal lines not being simultaneously detected. Vertical or horizontal lines can only be detected separately. This is due to the optical characteristics of the camera’s AF sensor and lens. 

If the maximum aperture of the EF lenses and EF-S lenses other than the lenses above is up to F5.6, all of the AF points function as cross-type AF points, and both vertical and horizontal lines are simultaneously detected.
